2 Pasadena helicopters crash; 6 injured

A crash involving two Pasadena police helicopters left six people with minor injuries Saturday.

The collision happened around 4 p.m. at the Pasadena Police Department heliport at 2175 Yucca Lane in Altadena.

In a press release, Pasadena police said it was, "an incident where their rotator blades were believed to have touched during a maneuver at the police heliport."

The six injured, five police officers and one civilian, were taken to a hospital for evaluations.

Both OH-58 aircraft sustained extensive damage, police said. One helicopter was on routine assignment to calls for service and the other was assigned to the USC-UCLA game at the Rose Bowl. Each helicopter had a pilot and an observer. Two of the injured were not on board.

It's unclear if the weather may have been a factor in the collision.

The National Transportation Safety Board will conduct an investigation.
